GloBrass,ECO BRASSLeadfree brass ... mitsubishicopper.com

CW724R, CB768S. GloBrass and ECO BRASS are environmentally friendly materials, complying with RoHS directive, ELV directive and Tap water quality standards. GloBrass is the new material whose copper content is close to general brass, the machinability and the strength are well balanced, it is possible to supply thinner bars, so it is recommended to massmarket segment which leadcontaining brass are applied.

Development of a LeadFree Bearing Material for Aerospace ...

The main objective of this project is to develop a leadfree environmentally friendly copperbased bearing material for high speed/load applications. In this study, bismuth was selected to replace lead in alloy C93700, and two different leadfree materials were cast in addition to the standard bearing material. This comparative study is focused on mechanical properties, microstructure, and tribological characterization of the candidate replacements for the leadcontaining bearing alloys.

Applications: Industrial Casting Alloys Copper

The 11 ppb limit under NSF Standard 61 is lower than the 15 ppb of the Lead and Copper Rule because EPA assumes that as much as 4 ppb of lead could be picked up from other sources. A California Proposition 65 consent judgment has established an even lower limit of 5 ppb lead in California, as determined by the same NSF Standard 61 test protocol.
